Abstract

Spindle vibration is an important factor affecting the machining accuracy of machine tools with the vibrations reflecting a large amount of working condition information about the machine tool. A vibration transmission mechanics model was developed to model the coupling between the shaft and the chassis to improve machining accuracy when measuring the acceleration of the main shaft outside the shell. Hertz theory was used to calculate the bearing stiffness because of unknown parameters in the mechanical model. The base stiffness was calculated using Ansys and Hooke's theory. The vibrations of a 170XDS20Z11 motorized spindle were analyzed with the results showing that the spindle vibrations can be efficiently and accurately measured by measuring the shell vibrations. This theory can be applied to indirect measurements of spindle vibrations to improve measurement accuracy.
